Why not go for a 7' Heavy action rod. This would give you a good all around rod for jigs, frogs, heavy t rigs, heavy top waters and would still be able to "punch".
I say 7' ranther than 7.5+ or 8' because it is a much more versatile length. Especially for jigs and frogs.
I would be hesitant to get a rod for something I don't do much of, thereby abandoning an opportunity to get a high end rod for what you do the most of.
A lot of guys use shorter rods for punching. And besides you can use what you have for now with senkos and flukes.
Use this rod for a while, and you can see weather getti g a rod spexically for punching is needed or if you need to go another direction. The dobyns 705 or 735 would fit the bill for now.
